Something interesting on extreme sex size #dimorphism in early #hominins -- somewhat like #gorillas
Fossils reveal extreme sexual dimorphism in early hominins. The findings reshape views of their social behavior. A recent study has revealed that males of some of humanity’s earliest ancestors were much larger than their female counterparts. This marked difference in body size, found in both Aust
In this new Historical Perspective, Ken S. Toyama describes how the original definition of Rensch's rule, which has been overlooked for decades, can impact the way we study sexual dimorphism. Read now ahead of print!

Sexually dimorphic traits are wide spread among mammals and emerge during development through sex-specific gene expression programs. We know very little about these programs, including the genes, regulatory networks,and cell types that underlie them. It is also unclear when differences between the sexes emerge during organ development and howsex differences evolve across species.
I stumbled across an article today that reminded me of an exciting arte documentary from 2013. Worth watching!

Difference in body size (or sexual dimorphism) between males and females is common across the animal kingdom. One of the most extreme examples of sexual dimorphism is found in the cichlid fish species Lamprologous callipterus from Lake Tanganyika in East Africa, where males are 12 times bigger (heavier) than females.
